Characteristics of quadratic electro-optic effects and electro-absorption process in CdSe parabolic quantum dots

The nonlinear susceptibilities have been calculated theoretically for CdSe disk-like parabolic quantum dots by using a two-energy-level model in the strong-confinement regime. The confined wave functions and eigenenergies of excitons in parabolic quantum dots have been studied by solving the electron-hole effective-mass Schrodinger equation. The third-order susceptibilities of the quantum dots for quadratic electro-optic effects (QEOE) and electro-absorption (EA) process as a function of quantum dot size, relaxation time, parabolic confinement frequency, and pump photon energy have been also analyzed.
